IPC: H01H33/65
Filed: 1988-06-23
Abstract: PURPOSE: To increase breaking capacity by fixing a permanent magnet to a contact containing a moving track, without mutually corresponding two hot spout with respect to two arc roots, and blowing the arc roots toward hidden positions to ensure easy arc extinguishment and current shutoff. CONSTITUTION: When a rotary switch is open with the rotation of a shaft 22, arc roots 48, 50 locked onto fixed contacts 14, 16 are blown with the action of the magnetic field of a permanent magnet 34 and moved on a cylindrical outer periphery 42 to form arc root moving tracks. Hot spots, corresponding to the arc roots 48, 50, are moved to hidden positions 52, 54 and, when arcs 44, 46 are extinguished naturally and transferred into a zero current, optimum reignition preventing conditions are obtained, so that no thermoelectric discharge occurs at the hot spots 52, 54 on the side opposite to a knife blade 28. In this way, the possibility for reigniting the arcs 44, 46 is prevented or restricted, when recovery voltage develops and breaking capacity is increased.

Abstract: PURPOSE:To recover automatically the stop of output for an electronic device, by detecting a hit of the output due to the break of a power supply of the electronic device having a microcomputer and then controlling the microcomputer which controls said electronic device. CONSTITUTION:A synthesizer 8' consists of a synthesizer circuit 5 containing a microcomputer 4, and the output of the synthesizer 8' delivers the prescribed phase gain, etc. via a phase control detecting circuit 14. If a power supply 7 has a hit, the set information stored in a RAM3 within the computer 4 is erased. Thus the output of the synthesizer 8' is stopped. A detecting circuit 9' detects this output stop of the synthesizer 8' and then applies the signal break information to a microcomputer 6. When the hit of the power supply 7 is recovered, the computer 6 delivers a control signal at a time point of the hit by the information of the circuit 9'. Thus the computer 4 is controlled to set again the circuit 5. In such a way, the output stop of an electronic device can be recovered automatically.
